When I finished out the inside of my shop a couple years ago I split off a 42' x 36' heated work area which I added better lighting.
In this section we installed 3 rows of T-8 florescent lighting. Each row has six 4' fixtures with two bulbs each for a total of 36 bulbs. The bulbs are 32W each, for a total of 1152W
I choose 6500K (daylight) bulbs to best represent colors. Each bulb puts out 2700 lumens, so I should have a total of 97,200 total lumens (not counting several sections of lighting directly over workbenches) or about 64.3 lumen / square foot or .76W / SF.
It is good to work in. Much better than most shops I have been in, but not quite as bright as some others. The white metal liner on the ceiling helps alot.
I thought about the HO lighting, which would have been better, but much more expensive. At the time we built a partition wall, insulated and finish metal sheeted all walls and ceiling, hard plumbed in air, added ceiling fans with wall controls, etc., so skipping the HO was one of the areas I saved a few dollars.
I think I have about $500 in all of the lighting materials.
The fixtures are from Lowe's as I recall. They do not hum on start up and even if I have the heat off they start up easily and get full bright quickly when cold.
If I had it all to do it again I would probably choose the same, but if I had it to do as a stand alone upgrade, I may splurge and try the HO's.
